In the work the current state is analyzed and the relevance of investigations of the process of magnetic pulse welding of flat
parts from similar and dissimilar metals is confirmed. The results of investigations of possibility of realization of magnetic pulse
welding of flat specimens on the modified serial installation N-126A by means of experimental pancake rectangular inductor are
given. The scheme of the process is given. The technology of producing joints of flat metal parts with a thickness of 1.0...1.5
mm from similar materials from aluminum A5N and AMg2 alloys, as well as from dissimilar – copper, A5N and AMG2 alloy
with stainless steel 12Kh18N10T (hardened) is described. The carried out metallographic examinations showed that common for
magnetic pulse welding of similar and dissimilar metals is a specific joining of welding plates in the areas equidistant from the
center of the flat coil of the inductor. The thickness of the moving plates decreases, and the microhardness in the welding zones
increases. The quality welding was fixed within the two-zone shape of joining. The quality of the welded joint was evaluated
by the results of mechanical strength tests. 10 Ref. 1 Tabl., 9 Fig.
